The legislative committee looking into the lane closure scandal on the George Washington Bridge has received a federal subpoena involving a former top Port Authority of New York and New Jersey official.

People close to the Bridgegate case tell The New York Times that charges in the case might be possible against associates of Gov. Chris Christie under a section of fraud law involving the use of property.

Even after a second report was released on the politically motivated lane closures at the George Washington bridge, legislation to overhaul how the Port Authority of New York and New Jersey is governed remains unsigned by both state’s governors.

It has been more than a year since the lane closure scandal on the George Washington Bridge, and a legislative committee has been investigating why the three access lanes were shut down – snarling traffic.

New Jersey Gov. Chris Christie will not be on the ballot Tuesday, but he will face the first major test of his national electoral might as voters head to the polls in nearly a dozen competitive governors’ races.

Documents first obtained by CBS 2 showed 11 Port Authority police officers on duty at the George Washington Bridge during the late closures had safety concerns, and lawmakers on Thursday wanted to know why the concerns were silenced.
